MACI knee surgery cost and insuranceMACI is a two-stage knee cartilage repair, so costs rise with the biopsy, lab cell expansion and later implantation rather than a single operation. In 2023, 89% of cases were approved on the first insurance submission, with approval typically taking 25–30 days.MACI is a two-stage knee cartilage repair, so costs rise with the biopsy, lab cell expansion and later implantation rather than a single operation.

High tibial osteotomy recovery and joint preservationHigh tibial osteotomy shifts load away from a damaged knee compartment and is best suited to younger, active patients with correctable medial osteoarthritis. Recovery takes months, full weight bearing depends on fixation and healing, and long-term success is strongest when arthritis remains localised.High tibial osteotomy shifts load away from a damaged knee compartment and is best suited to younger, active patients with correctable medial osteoarthritis.

Can chondroplasty or an unloader brace helpChondroplasty trims and smooths damaged knee cartilage to ease catching and irritation, but it does not regrow cartilage; outcomes are best in isolated grade 2 to 3 lesions, not grade 4 disease. An unloader brace can reduce one-compartment load and pain when varus or valgus malalignment is driving symptoms, but…Chondroplasty trims and smooths damaged knee cartilage to ease catching and irritation, but it does not regrow cartilage; outcomes are best in isolated grade 2 to 3 lesions, not grade 4 disease. An unloader brace can reduce one-compartment load and pain when varus or valgus malalignment is driving symptoms, but it cannot correct alignment.

Which knee cartilage repair fits your situationKnee cartilage repair choice is driven by defect size, bone involvement and whether treatment is single-stage or staged. OATS or mosaicplasty uses the patient's own osteochondral plugs for small focal defects of roughly 1 to 4 cm², while OCA uses donor tissue when the defect is larger, post-traumatic or involves…Knee cartilage repair choice is driven by defect size, bone involvement and whether treatment is single-stage or staged. OATS or mosaicplasty uses the patient's own osteochondral plugs for small focal defects of roughly 1 to 4 cm², while OCA uses donor tissue when the defect is larger, post-traumatic or involves significant bone loss. AMIC is a single-stage marrow stimulation with a collagen membrane; MACI takes two stages but has 15- to 17-year follow-up data, while head-to-head AMIC-vs-MACI ev...

Cartilage repair or knee replacementThe first split between cartilage repair and knee replacement is whether damage is a focal defect in an otherwise intact knee or diffuse wear across the joint. Joint-preserving treatment fits localised lesions, often in younger or active patients, with alignment, meniscus status and stability shaping the plan. Smaller focal defects…The first split between cartilage repair and knee replacement is whether damage is a focal defect in an otherwise intact knee or diffuse wear across the joint. Joint-preserving treatment fits localised lesions, often in younger or active patients, with alignment, meniscus status and stability shaping the plan. Smaller focal defects under about 2 to 4 cm² may still be treated with microfracture, but the SUMMIT trial showed MACI gave better 2-year pain and function for larger defects. OCA addresse...
